A twin girder crane system is the heavy-duty choice. The twin girders are welded together in a triangular construction to stabilise operation when handling loads up to 1500 kg.
The twin girder crane is optionally equipped with motorized trolleys to automate the travelling motion of the girder and/or hoist. With heavy applications, a motorized girder is recommended. The two-speed motorized trolleys can be equipped with a frequency converter for more options.
